I try to create a poll in 2.7.1, but I never see the poll.
It shows that a poll has been created, but I can't see it to vote.
This post has a poll that I tried to create. Am I doing something wrong? I press the CREATE POLL link and input the information then press the UPDATE button. Is there something I'm missing?

After testing this further, I'm still having the issue. I fixed the lines as you suggested, and rebuilt the theme and did the consistency check. This fixed the existing polls, but any new polls are the same as before. They do not show up.
